THE CANNA. 



Sir, — I received two bulbs of the Canna from the Fruit Glrowers' Association. One of 

 them is growing vigorously in a pot in the open air. The leaves, however, partly die off 

 after a while. Does the wind hurt them in swaying the leaves, or should it be kept in the 

 house only ? 



John Mubllek, Waterloo, Ont. 



The Canna is a plant very easily propagated, either from seeds or by the 

 division of the bulbs. If by the latter mode, each portion should have both 

 buds and roots attached. The pieces may be planted in four-inch pots and 

 grown in the heat, but this is not necessary. They will also succeed if planted 

 in the open ground. Those which have been started in pots should be planted 

 in the open ground as soon as the weather is fit. Plant singly in a good depth 

 of rich soil with plenty of moisture. They ought to have warm, sheltered loca- 

 tion, where the wind will not play too freely with the leaves. In the autumn 

 after blooming, they should be lifted and stored away in boxes or pots of earth 

 for another season. 



BOOK ON SHRUBS. 



Sir, — Could you tell mc where I can procure a small book on the cultivation of shrubs ? 



M. F. Smith, Port Hope, Ont. 



Not knowing of any book especially devoted to this subject, we referred the 

 inquiry to Mr. Elias Long, of LaSalle, N. Y., editor of the Popular Gardening 

 knowing that he has written a good deal under this head. 



He says that in several of his books, which have been published, he has paid 

 more or less attention to this question, and refers us to his larger work — " Orna- 

 mental Gardening for Americans" — which can be procured from the Rural 

 Publishing Co., for $2 ; also to a more recent work of his, entitled " Landscape 

 Gardening," which is sold by the same concern for 50c. 



SHOT LEAF FUNGUS. 



Sir, — I have been a subscriber to your valuable journal for a number of years and with 

 profit. I would be glad if any of your readers could tell me what is the trouble with my 

 plum trees and if there is a remedy. The leaves rust, dry up, and fall off after the middle 

 of August. Some of them are now (Sept, 7th,) as bare of leaves as in winter. German 

 Prunes are the worst effected. I feel anxious about the trees as I am just starting fruit 

 growing for a living. I enclose sample of the leaves. 



Alexander Johnson, Gollingwood, Ont. 



We shall be glad if any of our readers will give their experience under this 

 head. The leaves sent us Ijy our correspondent are affected with what is known 

 as Shot Leaf fungus (Septoria Cerasina), which was described in the Canadian 

 Horticulturist of 1890, page 315, to which we would refer our readers.
